-------------------------------------

two views are introduced

exposition vs expectation
required vs provided

A contract records the benefits and the obligations
the contract describes what is the acceptable results and contributions for a task described

The client formulates the contract, instructing the provider on what functionalities are going to be used.

Shallow Changes are divided into two categories
  • contractual invariance changes: a simple mediation would do the trick
  • contractual evolving changes: changes that require revisiting the contract but do not require changes in the other party
